Get the morph target error values. This is an error value for each morph target, which indicates how much error you would introduce when disabling that specific morph target. It can be used as some sort of LOD system, where we disable morph targets that are marked with an error below a specific threshold. Keep in mind that the first morph target always contains the means, and is always active. So actually you have to +1 the index.
The array view of the error values.
